Abstract
In previous chapters, we have learned about the equilibrium of rigid bodies loaded by concentrated forces and moments. In this chapter, we will discuss the difference between the concentrated forces, i.e., force acting on a body at a given point, and the distributed forces. It is obvious that the notion of a concentrated force is a simplification of the load acting on a small area. This may be a valid representation when the area of the contact between the load and the body is small. However, when the contact area is not small, relative to the rigid body size, we have to account for the actual force distribution.
